The Biodiesel Magazine web site provides a map showing the location of U.S. and Canadian biodiesel plants. At this writing (late April 2009) the web site shows approximately 103 operating U.S. plants, along with 47 plants or 31% of the total that are idle. Another 14 are reported to be under construction. Biodiesel plants are more widely spread out than ethanol refineries. U.S. plants are heavily concentrated east of the Missouri River (including a substantial number in East Coast states), and in Texas, California, and the state of Washington.
